When iron loses three electrons it becomes ferric (Fe3+) ion
Iron is a metal, and is made of iron atoms. When it reacts to form a compound the iron atoms will lose electrons and become cations, either Fe2+ or Fe3+. All metals form cations when they form ionic compounds.
Two or three electrons are lost.

In the formula Fe2O3, the iron ion present is Fe3+. This means that each iron ion has a +3 charge, which balances with the -2 charge on each oxygen ion in the compound.

The correct name for the Fe^3+ ion is iron(III) ion.

The charge of the Iron(III) ion is +3. This means that the Iron atom has lost three electrons to become more stable and achieve a full outer shell of electrons.
The iron III ion is Fe3+
There is no iron ion in SCl3. The charge on the scandium ion is 3+.
double decomposition
it should lose 3 electrons
An iron atom is attracted to a sulfide ion because of the opposite charges between the two ions, creating an electrostatic attraction. In contrast, a zinc ion has a neutral charge, so there is no significant attraction between the zinc ion and the iron atom based on charge interactions.
Hemoglobin contains a heme group with an Iron ion attached to it. This iron is what binds to O2.
